Finally, I got the 1,00,000 loss amount back from the broker due to their technical fault.

This thread Will tell you What the process is to claim your amount.

Recently for a Full day On Dec 5, my broker terminal was not working, even not on call. I have some open positions Due to which I faced loss.

Now You have to do the following:

1) Always take screenshots of the errors
2) Write down the Symbol, price etc Which you want to trade at that time
3) Make Computation of loss properly with time

Now mail this to your broker, 99% broker will not give solution or your loss amount. Wait for min 3 working days

Now You have to file a complaint to NSE

Which I already tell in my earlier

Just make an account and enter your all details
You have to attach :
1) Mail with the broker
2) Error Screenshots
3) Computation of loss

And Wait for a few days and Now see the magic
